Objectives:
The authors studied the prevalence of histological thyroid gland invasion in laryngopharyngeal cancer and the preoperative endoscopic and CT signs predictive of this invasion.
Patients And Methods:
Retrospective study of patients with laryngopharyngeal squamous cell carcinoma (T3 and T4) treated by total laryngectomy or total laryngopharyngectomy associated with concomitant total thyroidectomy or ipsilateral lobectomy and isthmectomy.
Results:
Eighty-seven patients were included. Eleven patients (12.6%) presented thyroid gland invasion. Subglottic tumour extension greater than or equal to 10mm (P=0.008) and cricoid cartilage destruction on CT (P=0.001) were statistically correlated with histological thyroid gland invasion. An intact appearance of the laryngeal cartilages on CT was associated with a low probability of thyroid gland invasion.
Conclusion:
Thyroid gland invasion must not be underestimated in patients with advanced laryngopharyngeal cancer. Preoperative CT is an essential part of the preoperative work-up. Thyroidectomy must not be performed systematically.
